Smartphone-Based Platform for Secure Multi-Hop Message Dissemination in VANETs

Area of Science:

• Computer Science
• Electrical Engineering
• Transportation Systems

Background:

• Vehicular Ad-hoc Networks (VANETs) are vital for Intelligent Transportation Systems (ITS), enabling vehicle-to-vehicle communication for safety and entertainment.
• Current VANET realizations are hindered by high costs, lack of standardization, and limited smartphone platform capabilities, especially in multi-hop communication and security.
• Existing research often relies on simulations, lacking real-world performance evaluations on smart devices for secure message dissemination.

Purpose of the Study:

• To design and evaluate a fully on-device platform for secure multi-hop message dissemination in VANETs using smartphones.
• To address the critical requirements of multi-hop communication and integrated security services for VANETs.
• To provide a practical, infrastructure-less solution for secure message exchange in intelligent transportation.

Main Methods:

• Developed an on-device platform integrating a location-based protocol for relay node selection and retransmission criteria in VANETs.
• Incorporated a novel certificateless cryptographic scheme for data integrity and node authentication.
• Focused on practical implementation and performance evaluation on smart devices, moving beyond simulations.

Main Results:

• Successfully designed a platform enabling secure multi-hop message dissemination on smart devices.
• Demonstrated the feasibility of using smartphones as nodes for advanced VANET functionalities.
• Validated the effectiveness of the certificateless cryptographic scheme in an infrastructure-less VANET environment.

Conclusions:

• The developed platform fills a critical gap in practical, secure, and multi-hop VANET communication using readily available smartphones.
• This approach offers a cost-effective and scalable solution for enhancing intelligent transportation systems.
• The findings pave the way for more robust and secure vehicle-to-vehicle communication networks.
